Constituent system

A constituent system (also subsystem or component system) of an SoS forms a component or part of it. It can compose an organisational, human or technological unit, e.g. a division in an enterprise or an information system.

Realtionships between the constituent systems with respect to their governance, technology standard operating procedures, training and usage are crucial for a successfull System of Systems implementation.[1]


Constituent systems of an SoS have the following characteristics:[2]

  • Operational independence
  • Independent governance
  • High heterogeneity
  • High level of reuse

These characteristics are partly transferred to the corresponding SoS.
